Good mount for iPhone in Tesla
Size: Upgrade - For Model Y Juniper/Model Y/Model 3
Easy to use mount. Helped provide additional visibility while driving. Sticks really really strong to the surface. Also have an option of ac vent mount instead of sticking it on dash or back of screen. Strong durable material not plastic.

Versatile quality product.
Size: Upgrade - For Model Y Juniper/Model Y/Model 3, Size: Upgrade - For Model Y Juniper/Model Y/Model 3
The beauty of this phone holder in my Tesla Y is that it can be moved from corner to corner based on needs without worry of sticky glue issues… current setting is lower right corner and happy with things so far. Will absolutely update if my feelings change but so far I’m stoked with the purchase. Also the discount didn’t hurt either $$
